The official Japanese Pokémon website has a presentation of the Pokémon Booth at the Next Generation World Hobby Fair '20 Winter. Translations follow:

The Next Generation World Hobby Fair '20 Winter

The Next Generation World Hobby Fair '20 Winter will be held at four locations across Japan starting Sunday January 19th. There, we will present the latest Pokémon info, which of course includes info on "Pocket Monsters Sword/Shield", but also on the "Pokémon Card Game", the "Pocket Monsters" anime, and more!

The Max Raid Battle Experience Section
In the "Pocket Monsters Sword/Shield" section you'll be able to experience "Max Raid Battles" against Kyodaimaxed Sekitanzan and Laplace.
Those of you who challenged Sekitanzan (Kyodaimax form) will be given a serial code with which you can get a Kyodaimaxing Sekitanzan, and those of you who challenged Laplace (Kyodaimax form) will be given a serial code with which you can get a Kyodaimaxing Laplace! You'll be able to experience these battles even if you don't have a Nintendo Switch or the game, so make sure to try it out, okay?



*You will need the Nintendo Switch game "Pocket Monsters Sword/Shield" and a place where you can connect your Nintendo Switch to the Internet in order to receive the Pokémon.
*The system's user needs to be linked to a Nintendo Account in order to connect to the Internet. (The user does not need to be subscribed to "Nintendo Switch Online".)
*Please note that this is a one time gift for a single save data in a single game. It can not be received more than once.
*The expiration date for the serial codes to receive the Kyodaimaxing Sekitanzan/Laplace is Saturday February 29th 2020. Make sure to receive it before the deadline is up.
*For info on how to receive Pokémon, go here.

The "Pokémon Mystery Dungeon Rescue Team DX" Section
"Pokémon Mystery Dungeon Rescue Team DX" is the newest Pokémon video game, and it's set for release Friday March 6th. If you answer a special quiz exclusive to this event, you'll receive some items that will help you on your adventure! Not only that, you can also look forward to the Scarfed Pikachu that appears in the game dropping by this section in between the stage shows!



The "Pocket Monsters Sword/Shield" Max Raid Battle Stage Show
During the "Pocket Monsters Sword/Shield" stage show, four extravagant performers, some of them Pokénchi residents, will work together to take on a "Max Raid Battle". Make sure to come watch.

Battle Abareru-kun with the Pokémon Card Game Starter Set V!



Abareru-kun will be at the Pokémon Card stage show, and battles using the "Starter Set V" are going to take place there! Abareru-kun's opponents will be selected from you guys in the audience that are grade school age or younger. Master how to play the Pokémon Card Game and come battle Abareru-kun.

*We will lend you a "Starter Set V" you will use during the match, so there is no need to bring your own deck or any other equipment.
*The schedule has one person from the audience battling Abareru-kun per stage show.

The Special "Pocket Monsters" Anime Stage Show
Play fun games you know from TV, like "PokéRiddles" and "Pokémon Shiritori"! We'll have extravagant prizes too. The super popular Pokénchi residents will be there during the show at the Tokyo fair!
